Chance events coupled with positive feedback

"Brian Arthur, an economist concerned with nonlinearities at the Santa Fe Institute, wrote that chance events coupled with positive feedback rather than technological superiority will determine economic superiority - not some abstrusely defined edge in a given area of expertise. While early economic models excluded randomness, Arthur explained how "unexpected orders, chance meetings with lawyers, managerial whims . . . would help determine which ones achieved early sales and, over time, which firms dominated"."
